The update to Android 4.4 KitKat on the Galaxy Note 3 was a welcome change for the device, which had all the latest hardware, but lacked the latest software. However, while the update did a whole lot of good, it also brought upon an issue that disabled compatibility with third-party accessories.
Samsung began rolling out an update to fix the issue today. It also fixes a bug that prevented apps from writing to external storage on KitKat. Obviously this problem shouldn’t have come up in the first place, but it’s good news that Samsung jumped on it so quickly. The update’s build number is N9005XXUENB3. To check if your phone can grab the update, go to Settings -> General -> About device -> Software update.
